Question re: Water Temps
I ran into a new Z06 yesterday, and he wanted to play. Being happy to oblige, I dropped into 3rd and pushed the gas pedal to the floor. 
When I shifted to 4th tho, I noticed my water temp gauge was up to 215. Never having seen temps that high at WOT, I let off. Temps eventually came back down to 190s (it was @ 80 deg here yesterday) while cruising around town.
My question is what kind of water temps do you FI guys normally see at WOT? Is outside ambient temp a factor? What's the upper limit we can push to before it's considered "unsafe" for the motor?
BTW, I have AEM 1052, Koyo rad w/H20 & water wetter and fully built short block.
TIA

best upgrade you could do is lower fan switch and thermostat -
and yes we see those high temps here in florida - but with the mentioned mods it really seems to keep cooler.

Something tells me you did not re-calibrate the EMS thermostat stettings... PM "timg", as I believe he has the settings somewhere...
You need to re-calibrate some settings in an EMS table in order for the get the correct reading (it is wrong from AEM). Without re-doing the settings, the h20 temp will read 15-20 degrees hot.
As long as your fan is kicking on and off, the switch is working fine. I believe the Mugen one switches on at around 185, I believe. So, idle the car up, and see what your gauge reads when it flips on. If 15-20* higher than its supposed to, you need to correct your settings. My stock fans did not kick on until it read 215* without the re-calibration.
